Every time I eat anything with a lot of sugar, I start to get on edge, aggravated, mad, and down on my self. After all of those things go away I start to get sleepy and sometimes wanting something else sweet. Is this a sugar allergy?

Hi - just saw this thread while searching info on sugar allergies. I'm hoping to get more info on the biology/science behind sugar and physical reactions.

I noticed a couple of people mentioned they have trouble breathing after consuming sugar, as do I. For me any kind of sugar - cane, honey, maple syrup, agave syrup, apples, grapes, dried apricots etc etc - make me "high", I get itchy, mucous forms in my nasal passages, and then I have difficulty breathing (throat closes over, feels like a heavy weight on my upper chest, breathing becomes laboured - this can be brought on by eating as few as 5 raisins, or 1/4 teaspoon of sugar).

I have been tested as allergic to sugar but a lot of comments in this thread suggest that isn't possible - specific types/sources of sugar yes, but not sugar in general. I've read about fructose malabsorption but that doesn't seem to match up as an explanation either.

Sweet vegetables - carrots, yams, corn - are fine, but sweet fruit and all processed sugars are not. Any ideas on the chemical processes going on here? I assume there has to be some kind of logical explanation.

I'll spare you the details of all the tests and frustrations and simply say: in case anyone else searches "sugar allergy" and comes across this thread - check out Candida albicans as the most likely solution to overall sugar intolerance. Easy to test for, and easy to deal with, especially if you're down to eating nothing but meat and greens.
